Are you trying to make the `approxNearestNeighbors` method completely private? There is still a public overload of this method - which now shows up as the only method in the docs and just says "overloaded method for approxNearestNeighbors". This doc above does not show up. As a general rule, we should always generate and closely inspect the docs to make sure that they are what we intend and that they make sense from an end user's perspective.
